I wonder however whether it would be possible to remove the new command
line option and have the linker automatically decide between using
28-bit or 32-bit PLT entries ?

The problem is that decision on PLT entry size is done long before weactually output PLT entries.Fixing this would require a non-trivial code churn which I'm a bitscared to do...

Note that most of the people are probably ok with existing 28-bitentries (otherwise we'd know about this issue long ago).
