Love how when people find out that no one has reached a consensus on using one of the 30+ existing neutral pronouns, they create a new one.
The problem is that none of the existing pronouns has caught on, so people are still searching to find one that will. Perhaps we need a 'pronouns' thread to compliment the "Supporting Mx" thread
Some of the suggested pronouns are obvious non-starters, such as those that cannot be pronounced or do not fit into existing speech patterns, others sound too much like existing words. These aren't really standards, or even suitable to be put forward as standards, they are merely suggestions. We need to keep thinking about pronouns until we develop something that fulfils all the requirements, then we can promote it as our agreed standard with confidence.
Mx certainly is a good substitute for Mr/Mrs because it fulfils nearly all the requirements; the only slight niggle is that the pronunciation is not obvious until it is generally accepted as an abbreviation for a longer pre-existing word such as "mix" or better still "mixture". The abbreviation "Ms" also suffers from this problem, because very few people realise that it it an abbreviation for "mistress" - and that is how it should correctly be pronounced. (Before anyone protests, we don't pronounce Mr. as "Mer" or Mrs. as "Merz", so why should we attempt to pronounce Ms. as "Mees"?)
Thus we have:
Mr. = Mister
Mrs. = Misses
Ms. = Mistress
Mx. = Mixture
...which seem like a perfectly good set of standards worth promoting.
