Make sure BEP001 developers contribute to question of introducing "phase" for EPI acquisitions

[KirstieJane]

The discussion is happening at: bids-standard/bids-specification#128

My (@KirstieJane's) view is that this is another "BIDS 2.0" challenge (aka "I wish I had a time machine"). It would make more sense to use part-mag or part-phase for the EPI data, but as _bold is already a very widely used suffix (as @chrisfilo says in his comment bids-standard/bids-specification#128 (review)) it would break backwards compatibility.

I commented (bids-standard/bids-specification#128 (comment)) that we'd try to get a BEP001 consensus comment back by the end of 24 Jan, so please have a think about this before our meeting on Thursday. Thank you! ✨
