I for one would welcome consistent fatal errors for LSP violations,

Once again, nowadays warnings are converted to errors during development.
This change affects production only, where this isn't being done.
Have you considered testing
I have yet to see codebase with 100% test coverage. Better idea is to use
static analyzer. My objection is for remaining cases.
I don't understand what's the benefit of raising fatal error here. Code is
not lsp compliant? Cool, you will get hard error when calling such subclass
anyway. Until that call happens, there is no bug so warning is fine.

True, but I would think that after upgrading a library, one would at
least do a basic test of loading the code that uses the library to
see if it still works.

I disagree. There is a bug, but without a fatal error at compile time
you are less likely to find out about it until the relevant call happens.

Besides the benefit of finding bugs earlier, there is also the benefit
of more performance optimization opportunities that Levi mentioned,
as well as simplifying the PHP engine. 1
