You can avoid this easily on Linux by using versioning, like in .so
files. So you would end up with:
lib/lazvcl.1 -> lazvcl.1.0.3 (symlink)
lib/lazvcl.0 -> lazvcl.0.9.8 (symlink)
lib/lazvcl.so -> lazvcl.1 (symlink)
and linking either to exact version of library, or version 1, or just
any version. On Windows, this should be technically possible, too.
And you can turn off shared libs/packages in Delphi, too (in fact, I
never turn it on).
