I've been cutting down on plugin use and esoteric mappings because of similar reasons but 50 is really small. I still hover around 10ish plugins, some of them are language dependent to help with indentation. Some of them just aid in intergrating with tmux or git, make it just a bit easier to open a file (ctrlp), or some show syntax errors.
Without stuff like that I'm still fine should I find myself on a remote machine. But I don't see an issue with making myself more comfortable than just being 'fine' on my personal setup where I spend most of my time.
I think the key is to vet your plugin and mapping choices to ones that expand upon vim in some way and avoid those that override core functionality or prevent you from learning them. If you do that you should be fine without imposing an arbitraty vimrc length.
