If I type desiganted into the Allowed Access field or portugese into the Cuisine field, the suggestions should include near matches such as designated and portuguese based on an edit distance to known values. This might be difficult for combo fields that get their suggestions from taginfo, but predefined options from id-tagging-schema could still participate in the same kind of fuzzy matching as presets in the search bar or fields in the More Fields dropdown.

Fuzzy matching would keep id-tagging-schema from having to maintain an index of likely typos, as in openstreetmap/id-tagging-schema#266.
