As it is an addition of a method to an SPI interface, then no it will not
be breaking applications.
It may or may not affect integrations. The only implementations of
EnhancementContext
I know of are our implementations. So, certainly you could say that it
potentially breaks integrations. But
The fix for HHH-10801 added a method,
isMappedSuperclassClass(CtClass), to
org.hibernate.bytecode.enhance.spi.EnhancementContext.

Would an application implement EnhancementContext? I don't see anything
that would break, but I'd like to confirm before backporting HHH-10801 to
5.0 and 5.1.
