As a dev, service workers are a PITA and getting them to work with with our products is a bit of a hit and miss. Installable / pinnable web apps are only available if the original web dev has made them available. Web catalog and electron wrappers are for people who want to wrap apps and sites that are not nor ally available.

You do not need service workers to do what Web catalog/electron wrappers are doing:

google-chrome --app=https://example.com

firefox --ssb https://example.com (sadly requires enabling the ssb feature)

Sure, you can have a tool to create "desktop shortcuts" for the casual user, but this is not worthy of a commercial product.
