I generally agree with your points above, and these can be easily summarized by indicating that the patch will not wait for this, and suggesting that MITRE is not the only possible source: The security team does not assign CVEs, nor do we require them for reports or fixes, as this can needlessly complicate the process and may delay the bug handling. If a reporter wishes to have a CVE identifier assigned, they should find one by themselves, for example by contacting MITRE directly. However under no circumstances will a patch inclusion be delayed to wait for a CVE identifier to arrive. This puts the responsibility for finding one in time on the reporter depending on what they expect, and if they want it in the commit message, they'd rather have one before reporting the problem.
