Is it considered in acceptable taste to use machine-cut round-ended
tenons for through tenons on furniture? Does it depend on the style?

This isn't for anything I'm working on now; just for information. I know
it's my work and I can use anything I feel like, but what will it look
like to knowledgeable viewers? I don't want my tenons to look like brown
shoes with a tux.
