Two different measurements (time and Atlassian development processes) that are orthogonal.
Anything Atlassian does is mostly quite late and its integration story is so pathetic that it's unsurprising.
Try to have a bitbucket pipeline that pushes to confluence. Seems like a basic integration to have, after all, Confluence has an API (well, actually it has 3 different ones) so surely Atlassian would make a basic thing like "publish a wiki page" a thing you get out of the box.
Given Atlassian bought OpsGenie in 2018, this either somewhere between quite late and unsurprising.
