Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Sections (~1066 bytes added 📈 [gzipped])

name            parsed_size           gzip_size
site-purchases      +4294 B  (+0.3%)    +1066 B  (+0.3%)
purchases           +4294 B  (+0.3%)    +1066 B  (+0.3%)
domains             +4294 B  (+0.3%)    +1066 B  (+0.3%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.

Looks good to me! @dsas can you have a look before we merge it?

Works well for me 👍 . The site is marked as free but the menu stays as 'Business', but I think that's a separate known issue.

Nitpicky and unlikely to matter but the wording on the warning screen says "....continue with plan deactivation" which isn't exactly consistent with the wording elsewhere where we talk about removing plans not deactivating them.

I thought it'd be nice if the wording was a bit more reassuring to say something about the content being kept, but I guess if the content is dependant upon a plugin it won't be, so not saying anything about it (as is implemented) is safer.

Yeah, that's unrelated to this; it's a caching issue in Jetpack.
