Captain,

I'll start with a very obscure reference.
Ever heard of "The Little Sandy Review"
From 1960 something

A reviewer criticized a revival group for being too good technically. Generated a bit of controvery at the time

Anyway,
The Traditional musicians I am familiar with strive for technical excellence, just like everybody else.

They don't always achieve it, just like everybody else.

Some are virtuosi by any measure, some aren't, etc.

You are not doing them or their musical traditions any favors if you affect some sort of "primitivism" in your performances. It is patronizing.
