@stuartmorgan you were right that there was a missed null cast, I am still using the cast methods though, so the safeCast parameter is still used.

Isn't safe casting here (vs force casting to a possibly nullable type) wrong too?

Where is safe casting happening?

When I reviewed it last time, _cast was still actually doing safe casting (as?) any time safeCast was true. Now it looks like it's not which is good, but there's still a parameter called safeCast which seems even more confusing. Can't we just remove the parameter entirely now? It's only used in a condition that checks for the case where it would have generated as? Any, in order to prevent it, but that's now impossible for it to generate anyway.

LGTM other than removing a bit of dead code.

Testing label to see if it lands a "stuck" pr, not to fix tree, but to "un-stick" a good to land pr on a green tree.
