I think some antiX applications could go without a menu entry since they are available from the Control Centre. Some don’t make any sense as standalone menu items, some do. I mean you did it MX that you added NoDisplay=true to most of the .desktop files of such applications. antiX has a menu which coplies to the Freedesktop standard, it should work here, too.
My memory is fallible; we introduced the setting (NoDisplay=True|False) to antiX in 2013.
You might have a look at Menu Manager which has shipped as a standard app of antiX-Full since 2015. It uses that setting to enable a user to hide/show (unhide) items in the Applications section of the antiX menu, and also create/remove items in the Personal section.

The first 13 minutes cover using it for the Personal menu section, after that it shows using it to alter the Applications menu section.
