Classic Wiki Page

Good Day

We hear our customers struggling with the choice about modern page VS classic wiki pages.  Our users understand leveraging the modern UI the most is the recommendation, however our customers still find features in classic wiki pages not being present in modern pages or some common actions (i.e linking pages) easier in classic wiki pages.

Do we have an idea when would classic wiki pages be discontinued and if modern pages will be getting the same core functionality or equivalent classic wiki pages have? Thanks
