There's really no reason to DELETE them. I just created a directory /system/app.disabled moved everything I didn't want into there.
Doing so avoids the situation whereby you decide you want to put something back and have to go asking around for APKs.![]()
It is always good practice to make backups of files before you delete them. I did not follow this rule, I also had very few ill effects.(None after I did a reset). I was a very lucky that nothing went very wrong.
