Many people need more characters to hang when Optical Margin Alignment is turned on than what is provided by default. This panel should have settings to customize from the default. The workaround to add a space before the character you want to hang and then adding a huge amount of negative kerning, works, but seriously that's all we've got? That is not a real solution, nor is it efficient for multiple instances in multiple documents worked on by multiple people every week. The time used fussing with this alignment must add up to dozens of hours per month, just within our small group. This feature really needs attention. For example:

In typography, a reference relating to the main body of text, positioned at the bottom of the page. Footnotes are referenced by certain symbols (*, †, ‡, etc.), letters, or numbers, most often in superior or superscript form.

A footnote begins on the same page as its reference call, but it may be carried over to the bottom of successive pages. A short rule or additional space should separate the footnote from the text. The first line of each footnote is normally slightly indented.

Point sizes for footnotes are usually 7- or 8-point. By law, footnotes in financial forms, annual reports, prospectuses, and other SEC documents must be no smaller than the text size, which is 10-point.

The most common sequence of footnote reference marks is: 1. asterisk (), 2. dagger (†), 3. double dagger (††), 4. paragraph symbol (¶), 5. section mark (§), 6. parallel rules (||), 7. number sign (#). If more are required, they can be doubled up: double asterisks (*), double single daggers (††), double double daggers (††††), etc. However, when many footnotes are used, it is more practical to use consecutive numbers to identify each footnote.

The Story panel could have options such as "include all characters defined as punctuation in this font" or "only include characters defined as punctuation in this font" and even the ability to define your own list of characters. The characters defined as punctuation are already "known" to InDesign, see the Glyphs panel. It must be possible to link this definition that InDesign already "sees" to Optical Margin Alignment in the Story panel.

I know this feature was not developed for lists, but it could be very useful for lists with these improvements!
