Obviously you are right, there are no standards, but, I wonder: a dev who develops a project, despite there are no standards in any subject, should not introduce, to make at least a project interesting for those who appreciate and follow it, advertise and finances, a more or less respectable update schedule and establish, even with an approximation of a few months, a completion date (strictly avoiding undocumentable excuses) and above all to gain their trust???
But perhaps not even this is a standard.
