A site I may take over has a plugin that adds .html to the pages. I searched online but I’ve only found how to add it rather than why to add it. Is it needed? If I remove it, I’ll have to be careful with SEO / indexed pages and redirects. The site is running 3.x.x and 90% of the plugins have not been updated in over 5 years including this one. Before I update to 4.7.x, I am trying to understand the landscape (pros / cons) on why something could be used and if I need to find a suitable replacement for it.
