What exactly do you mean here by "getting a scholar to attest"? This
could range from a casual remark at tea by a famous mathematician who may
be notorious for confidently proclaiming statements that sometimes later
turn out to be false, to a published paper with some real work in it.
Attestations on the former end of the spectrum are probably easy to come
by, but do we really gain much from them?

Based on anecdotal evidence (discussions with friends who are in algebraic
geometry), "content" is the wrong word. There are plenty of algebraic
geometers around who would like to understand the material in SGA
(including SGA4 in particular) but are daunted by the amount of effort
that would require and the time that it would take away from their own
research. Those who do understand the material will readily acknowledge
that it would be good for a digestible version to be produced, but again
have more pressing projects.
In other words, just because nobody is fixing the situation doesn't mean
that everybody is "content" with it. Was the mathematical community
"content" with the status of the classification of finite simple groups
prior to Aschbacher and Smith's recent work? Some were, but a lot
weren't; just because people weren't working on it doesn't mean they were
"content."
And note that I'm talking just about rewriting SGA so that working
algebraic geometers can understand it better and perhaps use it in their
own research more substantially than by just quoting a few of the major
theorems; this is something that mathematicians would be more motivated to
do than simply "cleaning up the logical foundations." If they can't even
make time for the former, then they certainly won't make time for the
latter, but this doesn't mean that they are "content" with the logical
foundations.
