entrance=* looks like it has the “title” of the entrance, and there are several entrance types. 

Usually entrances have official or unofficial names, and just having “main” “service” and other ones means that the other standard types of entrances that one sees in daily life should be accounted for - leaving gaps in the tagging leads to bad tagging. 

if you are going to have main, & service, the idea of visitor entrance and employee  entrance  (to a large corporate building) is really common, as well as a handful of other standard entrance types. 

Student came to mind to me because is it a common entrance type in the country I am at, and guessed really low - apparently there are hundreds of thousands of elementary schools alone in Japan - each would have an entrance=student, let alone middle schools and high schools. 

We label car access doors differently (hood-bonnet  / trunk-boot ) and then discuss what is in them. Although this seems to be a little bit of a duplication, naming things what they are in the tag itself (as we do with many other tags - building comes to mind) and then refining via access= seems proper. 

If we are able to differentiate the entrances, then renderers can choose what class of entrances to ignore (aka don’t render entrance=house entrance=service entrance=emergency) rather than just choosing not to render access=private, as some of those might still be worth rendering. 

I thought this might prevent pollution of access=with inconsistent tags...

If it is truly a bad idea to create further entrance=* tags, then how to tag other kinds of various entrances (with tag combos) should be added to the entrance wiki so someone doesn’t just come and add a bunch of values w/o asking the tagging list.
