But why? It just doesn't make sense - that isn't how the fitting works


I know, but with mass produced fittings (probably from China) there are
always tolerance issues. PTFE takes up any imperfections in the
thread/olive/tube.


The olive does a pretty good job of that.

Why would you want to replace a metal/metal seal with a metal/PTFE seal?

I just don't get this "use PTFE regardless" approach - I've made
hundreds of compression joints without PTFE tape on a single one, and
have yet to experience a problem.
