I’d imagine they’re live updating the library paths in the binary headers, so anything shorter or equal to what they’re using is a simple rewrite, but longer is more complex.
It's so annoying how deeply UNIX packaging philosophy assumes that installation directories are something you hard-code at build time.
It makes me think of when Arch merged /usr/bin and sbin with /bin and sbin. Having them split made sense in a ton of scenarios that used to be very common, but increasingly the split was vestigial for most users.
But these days, "early boot" is handled by initramfs and we've all got drives large enough to not need the split anyway.
