Note that point 2, if you want real apostrophes, you can still use U+2019 (’) which is never interpreted as creating a wikisyntax for italics (when doubled) or bold (when tripled).

• The ASCII apostrophe is not a real apostrophe
• Inserting a space between would not be the correct orthograph for an elision that is normally glued with the first character of the following word without any linebreak opportunity between the two glued words.
• If you still prefer to use ASCII apostrophes, you can still glue them by inserting a wiki-separator that generates nothing but avoids the interpretation as italics/bold in the MediaWiki syntax. One way to do that is to write '<nowiki/>'
• But it just looks simpler to just use ’’ with U+2019... (note: you cannot always insert a wikisyntax in all messages, as they are not all parsed with MediaWiki, some messages become plain HTML or use different parsers in different languages (e.g. PHP, Python, Shell...) that also frequently have their own usage of ASCII apostrophes or require some escaping. Using U+2019 however should work everywhere (it's usually not needed in English, but even English typographs prefer the U+2019 curly apostrophe to the compatibility ASCII apostrophe-quote which has too many different uses and meanings, including when they are used as quotation marks in human text, even if programming languages usually use the same quotation mark for the first and last occurence in a quoted string not really read by humans but processed by programming language parsers).
• The curly apostrophes are usually better readable for end users, and are still found in plain text searches on all search engines (including the default search in MediaWiki).
• The ASCII apostrophe however remains used in page titles in most wikis without needing the addition of a redirect or needing to pass via a search result page, but is never needed anywhere else in the document bodies of human-readable text.
