Is it problematic to make ownership, grouping, and permissions of phpmyadmin as of website dirs?

I use Ubuntu 16.04 and my PMA version is always latest (I updae software regularly with cron). My question is this:

Is it problematic to change all inodes under phpmyadmin to have www-data as owner and group, and have all directories 755 and all files 644?

This is something that I might done as a byproduct of a bulk change operation for all content under /var/www/html and I am not sure, and don't know the code of PMA to assume if it generally should be problematic and would appreciate an opinion on this.

There is no need to have the files owned by the user running www-data. phpMyAdmin does not need to write to the files, so there is no reason to allow that.

In either case if you want to do that, just run chown -R www-data:www-data /path/to/phpmyadmin.
