Well it doesn't really matter because the wiki apparently treats them as the same anyway... It must be deliberate so I assume whoever wrote the code had a good reason and better knowledge of how mediawiki handle these things than I do.
https://github.com/openstreetmap/openstreetmap-website/blob/master/app/helpers/browse_tags_helper.rb#L44 seems to be the explanation, that the script that scrapes the wiki normalises on space.
Sorry, it normalises the keys to underscore, but the values have spaces as you can see in config/wiki_pages.yml
so the page names we link to have spaces.
This script ok for links to Wikipedia and other Wikis in the tags such as wikipedia
, brand:wikipedia
, wikimedia_commons
etc., but the tag amenity=place of worship
with spaces won't be rendered on the map as a place of worship. Looking at the set of tags, everything looks ok at first glance when we see the correct link, but this is what may cause us not to find out what is wrong without opening the editor.
So for example:
wikipedia=en:Open Street Map
and wikipedia=en:Open_Street_Map
is technically the same, but
amenity=place_of_worship
and amenity=place of worship
is not.
Relevant code in the wiki scraping script: https://github.com/openstreetmap/openstreetmap-website/blob/master/script/misc/update-wiki-pages#L93-L97
The OSM website treats underscores and spaces in links the same way, but in OSM tags it matters.

Click on the "place of worship" in the version 3 and "place_of_worship" in the version 4. You will see that the link directs you to the same Wiki page, even though tags
amenity=place of worship
andamenity=place_of_worship
are technically different. Visually we can see spaces and underscores, but due to the fact that there is a blue link to the Wiki page, it's hard to see that the tag is invalid.
