Agreed.
Equal Temperament has been the standard for 100 years, and is what is
normally assumed in the absence of other information. The Cents
offsets are then clearly defined relative to those note labels.
If you don't use that system, then there are huge numbers of
possibilities for temperaments, and everything dissolves into
uncertainty and confusion, especially if there is an attempt to
describe rings according to some (conjectured?) original tuning
scheme.
Apart from such situations as ringing the front 6 of 10, change
ringing bells are used only in their primary keys, and are usually
only "more or less" in tune with each other (according to any desired
temperament). They are never used in "distant keys", and they do not
have to fit in with other instruments.
For these reasons the previous discussions of temperament and the
colour of different keys (when tuning starting from the key of C),
interesting and very relevant as it is to conventional music, have no
relevance in terms of description, and very little relevance in terms
of how bells are used.
Tuners can tune a set of bells to achieve any desired key colour, and
perhaps they should be more adventurous in that respect.
But for unambiguous *descriptive" purposes equal temperament is
perfectly adequate and universally understood.
Anything else must end with confusion.
