Comment (by azaozz):

 53432.1.diff looks good.

 There's quite a bit of related discussion in Slack, see:
 https://wordpress.slack.com/archives/C02RQBWTW/p1623965403246200. Also
 related #53285.

 Thinking it may be good to show a warning that the plugin has been
 disabled. Looking at how that may work, seems it would need to get
 triggered on the next run, so perhaps saving something in the DB and
 having a function to show it once. Can possibly add a bit to the Plugins
 list table to show a notice when a plugin has been auto-disabled, but
 perhaps consider it for 5.9 :)

 For the future seems the best UX would be to interrupt the core upgrade
 when there is an incompatible plugin. Then tell the user (and/or send
 email) to either update or uninstall the plugin before upgrading core.
