PDAL has been around for about six years and this hasn't come up, so I
think this is a pretty unique ask. We calculate the bounding area all the
time with the existing code and it works fine. The time it takes is dwarfed
by the time it takes to read the file itself, with no other processing in
place.

Actually, no. The code is there for you to do as you wish. The data you
want is there, you just have to write a bit of code to fetch it.

I’ll ponder what the most viable option is for us: status quo with liblas,

If what you want is just to read a LAS file into memory, then there's no
reason not to use liblas if it meets your requirements.

Best,
