It is my intention to remove the redundant mentioning of healthcare:speciality= from the tables on the wiki article Key:healthcare:speciality. As the article is about the possible values of the key it seems unnecessary to me to repeat the key on every row of the table.
I would find the tables easier to read without.
Any reason not to do so?
Yes, Becaaause, it is easy now to copy e.g. healthcare:speciality=endocrinology and drop it into the edit pane.
With the case of specialty v speciality it ensures non from the other side of the Atlantic suffer a typo (someone might endeavor to change the 2200 cases of school:specialty to school:speciality and the rest of them with the healthcare:specialty tags.
I’m not a wiki expert, but the key is repeated everytime because of the {{Tag}} template. Removing it would break the wiki links pointing to individual values pages. And if there’s a way to keep the template while removing the repetition, I guess it would add more text in the source wiki page, which would just move the problem, making it easier to read for someone but more difficult to edit the page for someone else.
But again, I’m not a wiki expert, wait for other replies.
Nope, that is not realy a problem. We have the template {{TagValue}} for that.
Then I agree with the edit you proposed.
Well, it wasn’t until your post that I realized it is actually healthcare:speciality=* and not healthcare:specialty=* 
So, I would suggest leaving the page as it is.
I include the full tag on (most?) of the pages I create/rework/edit - ex. light:colour, light:count, light:flux, light:method, light:flux…
The long version healthcare:speciality=* can be copied from the wiki and pasted directly into the editor [edit:] (like iD or JOSM).
Same, i hope there is a validator rule for it in JOSM. Or a preset that autocompleted, for i fear i have used it wrongly too.
Seems like not, so I made one: openstreetmap/validators/typo_fixer.validator.mapcss at main · Lumikeiju/openstreetmap · GitHub
https://raw.githubusercontent.com/Lumikeiju/openstreetmap/refs/heads/main/validators/typo_fixer.validator.mapcss
I’ve build the tag with drop down list into my JOSM pharmacy custom preset (multiselect, with 639 pages at Taginfo only listed the most common here, quite a few double with veterinary medicine and homeopathy… another dicipline with multiple variations of typos floating around),
There’s several more keys that are vexing. They have both a colon : and an underscore _ . Start typing and depending on : or _ ID will happily fill the same suffix out. Such auto_typos are hard to eradicate.
But I’ve gone thoroughly off topic :o)
