Hi bob3160,
I cannot confirm what you say as final, as the new extension API has been announced
to arrive sometime in the forthcoming future, but has not materialized yet.
It was said the total amount of items to be blocked from a chromium blocker extension,
would then be restricted to around some 17.000 items,
which is far too low for a full blown ad-blocking extension to properly function.
So one would have to let quite an amount of preferred ads through
to get at that restricted number.
So when that situation arrives ad blocking can only be used through external means,
ike adguard for instance or that kind of external software.
Indeed assumptions, as you state, but not assumptions right out of the blue.
