Effectively, you should be able to use:

I am for both variants. If you want the "hard check" with exception on
error you use the "as" syntax, whereas if you want the "soft check" with
boolean result, you use TryIntToEnum.
IntToEnum could be added as an alternative to the "as" syntax for the
sake of consistency, if the demand is present.
But with my experience and knowledge of the compiler, the TryIntToEnum
variant will be harder to implement for me. I am a little bit struggling
with it.
