I mean... no one is forced to use an Electron client to access IRC, so. That's kind of one of the main benefits of using an open, standard protocol like IRC.
Slack used to have that benefit when they had their IRC and XMPP gateways online. I know there are clients out there that leverage the API to do the same thing, but it's essentially re-inventing the wheel covered by numerous existing IRC and XMPP clients.
