In fact, JOSM has a hidden and even-less-than-usual documented feature that does much of this. It is called "display filter" and you need to manually set the config option displayfilter=true to use it. What it essentially does is that it allows you to save any search (e.g. amenity=hospital,amentiy=pharmacy) into a named filter and then apply that filter to your data at any time. For each filter you can say whether objects matching (or not matching) the filter should be visible and/or editable. You can even stack filters on top of each other. However, the whole thing is a user interface nightmare. There are all sorts of things that can happen, for example what if someone has connected a pharmacy node to a footway and you switch your health filter on - then if you move the pharmacy you don't see that you are moving a footway too. Or what if you have the health filter on and accidentally tag your pharmacy as bakery - it will simply vanish and you will never know that it is still there "behind the scenes". And so on. This can all be solved probably but it will need a lot of testing. I believe someone is working on improving the UI at the moment. But it seems unlikely to me that this is ever going to be a newbie friendly feature...
