Comment (by peterwilsoncc):

 As noted on the pull request, I am still seeing
 [https://github.com/WordPress/wordpress-
 develop/pull/1696#issuecomment-929826429 fatal errors when testing this
 locally].

 Both `gutenberg` and `wpforms-lite` intermittently end up with either some
 or all of their sub-directories empty.

 There are backward compatibility implications but I am wondering if it's
 possible to switch to a series of AJAX requests for each step:

 1. Create the backup of the previous install
 2. Download the update from w.org
 3. Unzip the download
 4. Activate the plugin
 5. Restore if needs be

 As fetch returns a promise, it's offers quite a lot of control to ensure
 the process doesn't get ahead of itself.

 1. No requirements
 2. No requirements
 3. Requires 1, 2 be complete
 4. Requires 1, 2, 3, be complete
 5. Requires 1 be complete, 4 to fail
