Oh, I too thought those would be workarounds but they are not.
The first two say: "This means it will only reflow ONE THING AT A TIME. If the page has 50 paragraphs, you will have to tap once on all 50 to reflow the whole thing."
Just tap on the next paragraph when scrolling. Scroll, tap, repeat. Your thumb will do that automatically while you're still reading the paragraph above.
EDIT: I just tried the third one by zooming in on a few desktop sites and I'm impressed. Make sure text size is set to "tiny" in the accessibility settings. It definitely works for me™.

The third one simply does nothing for me.
