The problem to me with that approach seems two-fold:

1, companies all expect you to work in the traditional way with local repos etc. All their tooling is geared towards that. If experienced users who set the standards aren't being migrated over, then they'll reinforce that status quo, and so will people who learned on repl but were forced to migrate off (monkey ladder experiment style).

2., using older tools is a point of pride. There's definitely a strain of "if you use repl.it / etc. and not emacs / vim / vscode you're a noob." This obviously is toxic and not great, but it does exist, and acts as another obstacle to online IDE adoption I think.
