Extensions were a thing well before Chromium and I’m sure even the developers wanted them, so we got extensions.
There’s never been a precedent for extensions on mobile and Google knows they can get away without, because if they do they’ll have a hard time taking it back. And they really don’t want everyone to have ad blockers on mobile because they know mobile ads is what brings in the cash, and they know mobile is one of the places where ad blockers would be the most useful and effective because the ads are so intrusive and annoying.
