It's interesting that PennDOT was saying that flashing yellow arrows would be used for new and replacement signal installations in lieu of the doghouse signals.  However, it seems, at least in District 6, they are still using doghouse setups for new installations and there are random installations of FYA.  I'm guessing it's because they need to install two new signals (a FYA assembly and a second thru signal), whereas using the doghouse covers both the turning and thru movements.

From what I've seen, the FYAs have been going in at newly built and rebuilt intersections and most of those have been in more sparsely populated suburban to rural areas. I haven't seen any say in the city or more densely populated suburbs as of yet. I'm guessing in those areas, they need to be weaned off the doghouse before showing them something they haven't seen before and cause accidents.

It is the complete opposite in Pittsburgh. There are more FYAs going up in city limits than you can count.

I've actually seen at least one FYA in Philadelphia for right turns (15th & Arch), though they use it completely wrong.  It's a four section signal but the green arrow is never used.
