People may as well get used to `pcase'.
But `cond*' is supposed to be _better_ than `pcase', isn't it?
Otherwise, we will end up not with one, but two confusing pattern
matching macros and people will have to learn both.

I was confused when reading the examples you provided. Same for Adam.
So, at least two people are confused - it is not a "mere perception".

I tried to come up with some better notation that is not as verbose as
"constrain", but I cannot think of anything less confusing,
unfortunately.
