Of course not, especially diachronically speaking (affricates often
originate with consonant clusters). But such a situation is according to me
very temporary. When it arises, the phonemic cluster gets quickly
reanalysed as a single phoneme, in the sense that it's how people will hear it.

You need a straight mind to invent a twisted conlang.
