I like that approach.

I've had the mantra "inheritance is only for code reuse" and it's never steered me wrong.

Inheritance is only good for code reuse, and it’s a trick you only get to use once for each piece of code, so if you use it you need to be absolutely certain that the taxonomy you’re using it to leverage code across is the right one.

All ‘is-a so it gets this code’ models can be trivially modeled as ‘has-a so it gets this code’ patterns, which don’t have that single-use constraint… so the corollary to this rule tends towards ‘never use inheritance’.

It seems like OP is describing a shared interface, not necessarily inheritance.
