Of course there is a logic, it's just a logic that you don't like and 
therefore deny to recognize ;-)

So what's the problem?

Some may think about a specific feature being more of a geographic 
feature, some a physical landcover and some may not even get the 
distinction between the two. This complicates the life of all ;-)

You are implying there's an "obviously correct way" to make these 
distinctions, which is not the case. If you take a look at:

the "physical landcover" would be bushes for me and certainly not trees. 
You may disagree.

While I was working to improve the JOSM presets, the more detailed the 
(sub-)menus became, the harder it was to place specific items into the 
right menu - let alone to find the right group boundaries (aka menus) at 
all to remain understandable.

The more groups (aka keys) you have, the harder it gets to understand 
and remember each boundary (aka the rules behind it). The more detailed 
each specific group is defined, the harder it get's to place a new item 
into the existing groups, e.g. it may fit into two definitions or none 
at all.
