Sure, you could dlopen() different SONAMEs until you find one that works, and now you just have to somehow deal with the structs having changed between versions, and the prototypes of functions not being compatible, so yes it's technically possible but nobody is going to bother

The idea isn't to open dynamic libraries randomly but to open dynamic libraries you explicitly know they provide the newer than 3 years functionality you want.

It isn't some fantastic never-seen-before concept, it is how applications on Windows can use new APIs from Windows 11 while still running on Windows XP or how OpenGL programs can use APIs from OpenGL 4.6 while being able to run on drivers that only expose OpenGL 3.1.

Yes, and for the reasons I expressed it doesn't work that way for most libraries under Linux.

OpenGL worked on Linux last time i checked (a few minutes ago).

Linux isn't some special case that makes this impossible, the only reason for this to not work is libraries themselves not making it possible. But the blame lies with the libraries not with Linux.
