Maybe.

It's not like I'm forced to use the interleaves; they're just there when I want tight shifts, which most of the time is in circumstances where a double-shift isn't clumsy to employ.
It's worth emphasizing that the middle/big front shifts are a lot snappier and less disruptive than on modern wide doubles due to the relatively tight front ratio. So much so that sometimes, when I want a shift that's a little bigger than a 1-cog rear shift, I'll sometimes flick the front shifter instead of using a rear shift.

A multi-range non-interleaved setup with similarly-effective ratio placement and overall range is surprisingly hard to create. Modern doubles have to use quite wide-ratio cassettes to achieve similar range, even in 12-speed.
