I concur with Michael's opinion, notably the well stated 4 points process.
After a cursory review, I did not find any documentation, either as a README or in the wiki. I have also run the pricatdemo and got what seems to be working results but I have not ideas of what is expected. I then ran pricat and got only this message "No excel import history data".
Pricat does not seem to need much documentation but a minimum is expected
I did not a thorough review, but globaly this is very simple and seems well done, so for me it's only lacking documentation. At this stage I'd not ask to revert.
Now I'm more and more thinking about plugins and specialpurpose. When the pushPlugin Gradle task will be completed (not only in localhost), I'd prefer to have plugins available in an OFBiz common Maven repo (on our demo VM for instance). Then some of the current specialpurpose components and new components plugins would be maintained by their contributors, pricat would be a good candidate for that.
We could use something like what Pierre proposes with https://oem.ofbizci.net/oci-2/ (currently inaccessible with Firefox due to HSTS policy, but OK with Chrome) to promote those plugins. It would be good if we could have Pierre's work as a common OFBiz feature, again on our demo VM. The idea is to have the OFBiz project keeping control over this aspect. If a such idea gets support would you contribute your work to the OFBiz project Pierre? For now I start the discussion here, but if it gets more interest I'll start it again on the dev ML.
