Depends on the lens, IMO. My most-used filters are a 10-stop ND and a CPL, and I have those in 77mm and 82mm sizes that work with most lenses. Where the drop-in adapter if really nice is with lenses like my TS-E 17 and EF 11-24, where the front filtering options are a real PITA.

Filters aside, the question of is it ‘worth it’ comes down to the features and cost of the RF versions.
