Quick sanity check: I can just shatter all rare cannon modules now, right?

I've got one ancestral cannon module, two mystic+ cannon modules, and one unique cannon module. I have 2 fodder unique+ cannon modules ready for when my unique cannon module is ready to go from unique+ to mystic+.

So in other words, besides my two fodder unique+ modules, I'll only ever need epic modules moving forward for upgrades.

That means that I can just shatter any rare modules moving forward right? If so, I've been waiting for this moment. Now my cannon level will grow faster given my extra shards.

Anyway, just wanted a sanity check before I start shattering all my rare cannon shards moving forward.
