We at Sourcepole will be doing some development this fall focusing on 
various topics, among the most interesting ones perhaps stuff like 
editing, importing external WMS layers, visualizing height profiles.

I suppose Kanton Zug has a good example: https://services.geo.zg.ch/qwc2

I suppose the alternative is be to have one WMS request for each layer 
instead of one request for all layers, which is easier to cache but 
performs worse if no cache is available.

The codebase is modular, see [1], components are self-contained (as far 
as it makes sense) and can be individually activated/deactivated/replaced.
