The problem could be more that a non-technical person in the sporting club you've built the website for may not be able add new or updated content themselves without that WYSIWYG editor.
If you are a member at this club it's fine, but if you're just a local trying to help the club you wouldn't want to be involved in each content update all the time.
This is a super critical point.
I am a member and ran the site for 2 years prior to this change. I was the only person that logged in.
Honestly this technical solution isn’t for every scenario but I felt confident that nobody would be updating the site in WYSIWYG. Comes down to what you need. There are many tools for many jobs.
