The poll has ended. With six votes across Twitter and Mastodon the results are hardly representative. But it seems that a #CVE identifier for everything is a rare approach (1 vote). Most respondents create one only for important findings (3 votes) or never (2 votes).
There is also a comment on Mastodon explaining the logic behind this: if it’s a vulnerability that companies should patch ASAP, assigning a #CVE identifier improves the chances considerably.
