It may have been low-level, but from such a high-profile individual it
carries considerable weight.  It carries real risk of appearing to give
permission for inappropriate childishness - or worse.

I'm not sure the technical argument was particularly coherent.  I think
there is a broad desire to deprecate and remove the buffer cache.  I
think the "technical argument" comes down to "don't remove it, just
ignore it if you don't like it" which hardly seems like a good idea for
overall project management.
A much better (in my opinion) technical argument is that the buffer
cache (which isn't all that much code) can simply be copied into each
filesystem which really cannot be modified to use whatever the current
preferred abstraction is.
