I wonder if the bigger hurdle here is that you have to spend money to get into the developer program (unless this is waived for these kinds of apps, I couldn’t tell when trying to dig up an answer) I don’t know that effectively slapping an app shell around an extension is a big hurdle, but no other web extension store charges for entry, so that very well could be the real barrier here.
Mostly, no.
"You can request to have the annual Apple Developer Program membership fee waived if you’re a nonprofit organization, accredited educational institution, or government entity that will distribute only free apps on the App Store and is based in an eligible country."
"Fee waivers are not available for: Individuals and sole proprietors/single person businesses"
