Reno:

First, it's nice that there are only 15 and 20 amp models available, which IMHO is a great safety move.

Going back many years, entering a resi job and looking into the fuse box and seeing all 30 amp fuses, with a quantity of blown 20s on the floor was common.

Warm and 'hot' conductors were common, chasing 'opens' was common, and so were fires.

'S' fuses were installed as replacements, but a lot of people found ways to stuff a 20 in a 15 socket, or rip the adaptor out! The 'fuse/breakers' were around and installed. I remember many that were 'blown' more times then whatever there 'life cycle' was rated for.

Better than Edison base fuses?? YES. Better than 'S-Fuses'? YES. Forbidden?? No way.

BTW, up here resi fuse boxes are becoming real rare.
