Okay, fair, though please include something about it in the commit
log so that other folks with concerns similar to Mathias Krause's will
be answered:
https://infosec.exchange/@minipli/110632971830936754

I still think this version of the sentence is more readable:

However under no circumstances will patch publication be delayed for
CVE identifier assignment.

"patch inclusion" is less clear to me that "publication", and "be
delayed to wait for" is redundant: a delay is a wait, and "to arrive"
is just the assignment, which is the subject of the paragraph, so better
to keep the language for that consistent.
