I'm not asking you to implement a new accessibility feature, I'm asking you to stop *preventing* an accessibility feature from being used. Browsers already do this; you just need to stop telling them not to.

In this case a general solution is the right thing to do because:

• There's no reason to disable this
• Even if you have special fixes for the cases below, you're likely to miss other cases (and most users won't report bugs)
• Even if you special-cased it, the correct special-case would be implementing pinch-to-zoom, since that's what phone users expect

For specific problems:

• I was trying to click on a link in a list of links that are close together. Normally I would zoom in and then click, but zoom is disabled.
• Try reading an image like this on a phone (even in the zoomed-in view):
  

Here are some screenshots of Phabricator with this tag removed, as you suggest:

Here, I've zoomed in enough to read part of the description of a task:

Do you think this is better than how the site currently works on devices?

Oh, sorry, you just wanted maximum-scale removed.

Yes, the rest of the tag is good. I just don't want pinch-to-zoom to be disabled.

There are at least some nontrivial effects, like searching for text without "maximum-scale" can imply a zoom:

With "maximum-scale":

That said, I couldn't immediately find anything egregiously broken. I think iOS is ignoring this attribute in some cases anyway:

..although that post is from June 2016 and has a lot of words that I didn't read.

Concretely, I can zoom on my iPhone SE / iOS 10.2 regardless of the setting, and the text search case above behaves as though the attribute was not present.

Hopefully Android browsers will hurry up and ignore that tag too..

(Specifically, D17714 added user-scalable=no, which probably does the opposite of what this requested.)

I tested pinch to zoom, which still works. We just turn off the auto-zoom. I'll roll the server here and give a more thorough shakedown.

Oh -- but double-tap-to-zoom doesn't? 😕

Right. Do you use that?

(I am glad to see the auto-zoom-on-controls gone and don't care about any other zoom feature.)

No, I hate all zooming.

I am just intrigued that user-scalable=no actually means "somewhat user-scalable".

Rolling, so we'll see how accurate the simulator was.

ehhh, not sure about this. It's not worse, like I can pinch to zoom in Safari, but not Chrome.
