Many aren't ready to switch to ck5

ckeditor-lts seems to use a licensed version of ck4. it would be good for people to know that's an option for them. Assuming develop cost is the reason people aren't ready I would guess that this PRODUCT may push them into progressing their sites..

There's currently no packagist warning when using ckeditor4.

I expect we'll be using ckeditor4 for a long while yet. There's a lot of use cases that haven't been covered and edge cases to fully review. Also, we will want to keep ckeditor4 for archived content possibly for several years.

The archived or unchanged content should still be rendered with the same format it was published on. Changing text formats could introduce surprises. Before removal it will require scripting to change all the text formats (at your own risk).

I suspect it will be a very long time before ckeditor4 will truely go away. We haven't even started using ckeditor5 yet.

Agreed, will need to support CKE4 for a while. Seeing some issues particularly with migrated content coming from Canada.ca, and some existing data on sites being upgraded. CKE5 with it's new plugins are too restrictive. For sites with just new content authored in CKE5 it seems to work pretty well though.
