actually, speaking as a singer with decades experience, they do change for
male voices in both historical and choral editions.  Altos, tenors, and
baritones have to be experienced reading in three clefs, tho changes are
avoided, they are found at times.

Only when you exclude scholarly editions; those involved in early music
must walk both sides of the fence.

But when commercial interests enter the picture, yes, challenging the
reading ability of the targeted customer is a nono.

Thankfully we are talking an option, good to have options.  I like the
concept of a list of clefs, and a set of penalties for different
situations suggesting a switch.
