Server returns snippets even though client doesn't support them

[puremourning]

The completion request always returns snippet-type completions, even if the client initialisation request doesn't claim to support them.

Logs:

• Initialize does not include snippetSupport: true which should be interpreted as not supporting snippets (only plaintext)

@evidolob , @JPinkney, I am running into same issue and I noticed that it's part of your roadmap. I don't see any milestone or due date information. Could you please let me know if you have an ETA?
Thanks!

[JPinkney]

Not entirely sure if we have an ETA at the moment, it just depends on when we get the time to make the changes. Maybe @evidolob will have a timeline when he comes back from PTO

Hi,

I've also encountered this issue, and I must say that the current behavior is not very user-friendly. Specifically, I want to be able to disable this behavior entirely. The problem lies in how the server suggests placeholders and subsequently provides further completions in a snippet-like manner, which is not desirable in my workflow.

It would be great if there were a simple configuration option to disable server-side snippet suggestions, particularly for placeholder completions. This would make the language server much more customizable and user-friendly for various development environments.

Thank you for your work on this project, and I hope this feedback helps improve the experience for other users as well.
