Suggestion: delegatable -> delegable

[Boscop]

Regarding #[delegatable_trait]: https://english.stackexchange.com/a/13176

The New Oxford American Dictionary, Oxford English Dictionary, and dictionary.com reports delegable as derivative word of delegate; none of them reports delegetable as English word.

Also, delegable is the only translation of the German word delegierbar:
https://www.dict.cc/deutsch-englisch/delegierbar.html

(It's like integrable instead of integratable.)

And delegable_trait would be shorter to type :)

Uff :/

Though I like delegatable more than delegable, I'm not really looking to coin a new word here, so yeah, this will change in the future. Will see if there is a good way to deprecate it.
