While I don’t agree, I do think there’s merit to the arguments you made (edit remotely, change a line and forget about it). Many anti-IDE arguments boil down to “I like a particular workflow and want to generalize it to all contexts” which is weak (you made the choice, you do the work to integrate e.g. Maven dependency awareness with your hyper customized vim environment or whatever).

However, I don’t think your arguments are sufficient to outweigh the benefits that can be obtained by making a language platform with features that assume the presence of IDE support.

Either way, I’m just one person, so you do you.
