Mailman bundler is not recommended because it doesn't install the current development branches.
Mailman 3.1 is "close" to release (how close is for Barry, Florian and Aurelian to say, but the improvements over 3.0 in the dev branches are substantial). I strongly (as co-mentor :-) recommend using the dev branches.
I'm not sure how far bundler has been updated, but the kind of issue you are likely to run into is, for example, <https://gitlab.com/mailman/mailman-hyperkitty/issues/10> This is a problem with the environment that tox sets up for standalone testing, not with interoperability of current Mailman components with each other. However, as stated in <https://gitlab.com/mailman/mailman/issues/181> this kind of thing is generally not going to get timely fixes in static bundles.
Aside to devs: I think we should toxify the procedure at <https://wiki.list.org/DEV/SetupDevEnvironment>, and allow specification of a ref tuple for the mailman components.
