It's not about the forum, we don't have different forums for different formats. It's about the module catalogue and the planner.

We’re not discussing changes to MG’s organizational menus, correct?

We are. It was requested to rename the Serge modular section (we call universe). If I understand that right the Serge guy is not happy to have other 4U modules listed under Serge format and vice versa 4U manufacturers don't want to be listed under Serge.
E.g. the system selector top left navigation will have removed the entry Serge and exchanged with 4U.
Buchla will still have it's own entry because of the different width and they way the MG planner works.
