Meson invalid method called on boolean option #829

In commit 6502a67 , the extension_memory feature was changed to a boolean.

This breaks on line 45 in meson.build, where .enabled() is called on the option. The error is the following:

ERROR: Unknown method "enabled" in object <[BooleanHolder] holds [bool]: False> of type BooleanHolder.

I'm using Meson 10.2.

I have fixed this locally by simply reverting the option to a feature and setting the default to 'disabled'.

I can make a pull request if necessary but first, I want to understand why the change was made in the first place. The pull request #764 mentions removing the single quotes from boolean options, but this is not what was changed. It looks to me like this is a mistake but maybe I'm missing something?
