But I get annoyed when it stops me from running some small piece of Inline::C code that would (I believe) have executed perfectly well if the failing handshake check had not killed it
As an example of why that's not necessarily true, consider a simple XSUB which returns a value. It may return that value using a PADTMP, or it might return it as a mortal SV, which (behind the scenes) pushes a value onto the temps stack and updates the stack index. Between Perl 5.18 and 5.20, the type of the temps stack index changed from 32-bit to 64-bit. A "simple" XSUB compiled under 5.18 and run under 5.20 may well cause the interpreter to SEGV soon after returning.

Yes, sometimes you might get lucky. But I think the use cases for disabling the check are rare enough that its not worth adding such a feature.
