PR proposal: would a magic link / passwordless auth strategy be considered for merge?

[abevoelker]

I wrote this Devise extension that adds a :magic_link_authenticatable auth strategy that enables passwordless login via sending "magic link" emails. I was wondering if this is a feature Devise would consider merging into core?

Asking because I need to write more tests, and I'd rather avoid duplicating the effort if this could potentially be accepted into Devise (i.e. just writing the tests for Devise's suite now rather than my extension first, then porting them over to Devise's suite later).

This would be great.
