Markkos1992 advised me via a PM that he would not have a problem if you weighed in with this stuff on PA and DE.
Otherwise, I'm not sure I'd wanna dump a ton of these results on the board without someone asking for it first.
(Regions undergoing peer review aside!) 
For those who want to look into it themselves, the option is available.
For a more detailed description of just what it is I'm doing & how, and the rationale behind each search, see
this topic. There are a few more searches listed there; in this post I've only included those with results in PA or DE.
Old highway designation labelsgrep '^Old..[0-9]' $rg/*/*.wptWaypoints for roads that no longer have a name or no longer exist as a roadMainSt
If the old highway has a posted name or number, use that name or number (don't make one up), and label the waypoint according to the usual rules.
If US 30/Main Street becomes Main Street, then the label is MainSt, not something like OldUS30.
OldUS40
If the old highway has a posted name that mentions the old designation, then applying the above rule will result in a label like OldUS40 for "Old Route 40" if the route was formerly US 40.
There will be a good number of false-positive, legitimate labels here. I did see a few that looked like changes were in order, OldUS22 for William Penn Hwy, a couple OldPA86 labels.
I'm not sure how closely these rules (if it's a requirement & not an option) have been followed; there are a lot of examples where "OldRt" or "OldHwy", etc. are used if a road is signed as such in the field, or if that's the official name. (Although, Tim may have done it that way before these specific guidelines were codified...) May be something worth discussing in the forum. If you decide not to change some of these cases I won't cry about it.

If the cross road name has more than 3 words, use one of two options:
1. Pick out the two most important words besides the road type and use only those: Martin Luther King Boulevard becomes MarKingBlvd. Three words in total are included in shortened form.
2. Pick out one important word besides the road type and use it and the initials of the other words: Martin Luther King Boulevard becomes MLKingBlvd. Two words in total are included in shortened form along with initials of the rest.
An older style for 3-words road names was to have Two truncated words & one initial. E.G., Lisbon Falls Village Rd -> LisFalVRd.
This was later deprecated in favor of the rule quoted above. LisFalRd, LFVilRd, etc.

Mc[A-Z] tokens are included to filter out "Old McDonald Farm Rd" style false positives.
OTOH, McDonald is one word, so it makes sense to truncate it to
McD, rather than treat it as 2 for
McDon.

Ignore any non-essential direction specifier. N. 6th St becomes 6thSt. 33rd Avenue SW becomes 33rdAve. W. Seedy Lane becomes SeeLn.
NorPkwy | SouBlvd
But keep directions that are the main part of the road name, such as NorPkwy for Northern Parkway or SouBlvd for Southeast Boulevard.
What's a "non-essential direction specifier" and what are "directions that are the main part of the road name" can get wibbly-wobbly at times; use your best judgment. Many of these may be legit, but they're worth checking out. The SR#### examples may have visible road names they could be changed to.
IMO though, N/E/W/S are common enough abbreviations for their respective directions, and there are enough examples of this throughout the data, that I'm not going to call for every
WPondRd to be changed to a
WestPondRd.
