Back-ups on Lightspeed webservers

I back up my site using Updraftplus and recently (17 July) the automatic back-up has stopped functioning. The updraftplus admin includes a link to this page: http://updraftplus.com/faqs/i-am-having-trouble-backing-up-and-my-web-hosting-company-uses-the-litespeed-webserver/#wp-comments

I contacted my host and they are using Lightspeed and they recommend I implement the first and/or second changes to my site. I’m new to this side of WordPress and still working out how to make these changes without crashing the site.

My question is: Is there any chance these changes will be part of a WordPress update in the near future. I’m going to have to make these changes on several sites and it would save a lot of time and the risk of crashing sites if these lines of code were included as standard. I appreciate there may be reasons why this is not practical but if they are to be made it will save me a lot of work.
