Remove backspace, delete, etc., bindings from insert mode for consistency

[aral]

Further to #3671, if we’re going to stick with insert mode being for insertion only, the following bindings should also be removed from insert mode for consistency:

• Backspace
• Delete
• Delete previous word
• Delete next word
• Delete to start of line
• Delete to end of line

(The other option, of course, is to revert #3671. Either way, the interface provided should be consistent.)

I don't see these bindings as inconsistent with the removals of #3671. #3671 covers navigation/movement while these are deletion actions.

@the-mikedavis Deletion in insert mode? We have deletion commands already (mapped to d, etc., in normal mode). If our design constraint is that people should not be bringing their non-modal habits with them and that insert mode should do just that (insert), then these should go to. The modal way to do it, surely, is to exit insert mode and use the delete command.

If that’s not our design constraint, then why was navigation singled out and removed?

@aral you're taking the terms too literally. "insert mode" is for editing text. Inserting characters and deleting them. The reasons that navigation were removed were detailed in the PR's discussion. Take a closer read of the comments there.

Removing delete in insert mode would be madness.

When touch typing it is best practice to delete the entire last word if you make a mistake to improve muscle memory. Having to enter normal mode to do that would not be workable.

There's a "selection mode" and a "text editing mode". We could rename them but INS reads a lot better than TXE.

If you're trying to start a discussion about reintroducing those mappings then please do so instead of making a snarky issue :)

Helix is designed to work well with modal editing.
"insert mode" should be insert only. You can enter normal mode and delete characters with d, after disabling deletion in "insert mode".

If you want to do some deletion in "insert mode", you can add one line in your config.
What we're all talking about is 1 line in your config.

Done (#3865), but please understand this isn’t (an overly) ;) snarky issue. There is an inconsistency being introduced by this.

@YangtseSu Your tone isn't helping this discussion.
