This is about importing email from your non-gmail account INTO your gmail account. POP is simply the easiest way to do this, and just from GMail's own IMAP interface, it's pretty clear that IMAP is NOT reliable for this task...
The details in TFA are that you can add an external IMAP account to the gmail client app in Android. This does nothing for the gmail web ui, meaning you need something else for your external email.
Wouldn't mind exploring something akin to a web-based, self-hosted Thunderbird mail client giving a server hosted web UI for multiple email and nntp services. If if synced to desktop/mobile apps and/or had a decent mobile web UX, that would be gravy.
