Though I know I will lose some of my ad blocking apps.
Lose some gain more. I have gotten rid of all but WIPR with no increase in annoying adds but major improvement in site specific control within Safari/Safari Technology Preview itself. I haven't lost any functionality I needed or wanted just adjusted to new controls.
You won't necessarily lose any of your blocking
extensions, because they may have been replaced by
apps available from the App Store, although their functionality won't necessarily be identical.
For what it's worth, I lost AdBlock for Safari to decreased functionality and greed, but I replaced it with Wipr a few months ago after reading that joemike used it, and I'm thoroughly pleased with it.
I also use Roadblock because of its unique ability to block ANY HTML element in a web page.
