The same argument could be made for a wealth of other properties,
every bit as useful, depending upon what you're trying to do: whether
the method has in course, tenors together falseness; whether it has
palindromic symmetry; whether it has the usual flow of in and out of
course rows (particularly important in minor); etc.

By all means, include it as a field in a database, so those that are
doing things for which a particular property is germane can query it.
But making it a part of the name of the method just confuses things,
as whether A is like B depends strongly on the purpose for which you
are comparing them. For some purposes the important thing is that two
ducks have the same colour, but for others it is that their down is
