Jenkins plugin broken in version 4.0.0, when will Atlassian fix it?

[Hofer Jonas]

Dear community

First time poster here, so forgive my stupid question.
I haven't found a question regarding the recent release 4.0.0 of the atlassian-bitbucket-server-integration-plugin yet, so here is my question:

We use Jenkins with bitbucket on-prem and rely on this plugin.
The version 3.6.0 works properly so we are now downgrading the plugin to get a working build infrastructure again.

However, it's been 6 weeks since the release of 4.0.0 and there is no fix yet.
The information is all there: https://issues.jenkins.io/browse/JENKINS-72120

Is this usually taking so long for Atlassian to fix a plugin so we have to expect to wait for another month, or am I just spoiled with the reaction time of other vendors who fix stuff like this within a week?
