At http://www.taylorcraft.info/tcraft/proj207.jpg we see a restored
tailsection.

The bushing appears to have first been welded to a plate, and the plate
in turn welded to the tailpost. Is that what was done? Is this done to
help with alignment of the bushing? - Mike

That's one reason.
It is a lot easier to assemble (weld) the bushings jigged up solid on the
bench. How would you align and clamp up the bushing to the tailpost and
still be able to reach the weld area?

Often this apporach is taken on new construction just because it provides a
bit of space to allow for fabric without binding.

If the bushing were dammaged somehow and needed to be replaced, this also
spreads the new weld to the tailpost out over solid tube.

Not to worry. It looks like a good repair (from here anyway).
