A bit confused:
- I think there's a better way to have promote behave like identity if the input ring and new ring are identical.
- The commit that changes this file says
fix isPromotable ring family
This reverts commit 63d7fc7.
But that commit doesn't seem to have anything to do with this file.

the revert part of the message is an accident. will fix.
the addition of promote(XX',YY') is an unfortunate side-effect of the messy way that inexact fields are implemented in Macaulay2 (which one day I'd love to rewrite from scratch, because it's such a mess).
They're not actual functions though because they never actually get called, really one should make them dummy functions.

I don't mind keeping the old names if you don't want to change names in a bunch of places, but I don't think we should actively rename something camel-cased to all lower case. Also, maybe move these functions to where isPromotable is defined instead.

will do. not the most urgent thing right now.
once again, this is a draft.
