I know it wasn't designed this way, but it seems like it
is a bug.
The manual says nothing about brace expansion using IFS in any way, so it's
not a bug.

I didn't say the manual said that.
However, in expanding arrays you have the option where it does use the
IFS:
If the word is double-quoted, ${name[*]} expands to a single
word with the
value of each array member separated by the first character of
the IFS
special variable, and ${name[@]} expands each element of name to
a sep‐
arate word.
So it does say something about 'some patterns' inside brace expansion
using IFS in
this way.
So if I say <<<$(echo "${word{1..3}[*]}" ), it might be reasonable
syntax to support
such? I.e. for IFS=/, => "word1/word2/word3"
It would seem appropriate though redundant to have
<<<"$(echo "${word{1..3}suffix[@]}" ) would expand the same as
"word{1..3}"
i.e. word1 word2 work3,
I don't see the usefulness in having brace expansion's behavior changed by
IFS.

Do you see any usefulness in having it for array expansion?
