Hi – in the Lee Valley listing for their standard taper reamer –,180,42240,53317,54864 – they refer to it being useful for “back-tapering holes for through-tenon wedging”.

The seems like it would be an effective way to make extra sure chair stretchers don’t work their way out of their mortises. However, I haven’t seen this technique described elsewhere.

Is this a somewhat standard approach? Any gotchas I should be aware of?

Mmcc the picture says it all.
Your job will be to make a wedge that’s fills the gap nicely.
Always do a test run on new stuff I would go as far as cutting my test piece down the middle.To see what I made for my own peace of mind.
Good Luck

As mentioned in your other thread, I think that through boring legs and stretchers would weaken them unnecessarily.
I prefer this method and have had excellent results over time
