Do you see some workable solution? Tagging say shade=* tag would 
require ridiculous way splitting (in some cases, near every single tree)
and/or require massive conditional syntax.

shade=* also is implausible and would cause more negative effects

And super detailed data is more objective, easier to verify, usable also for
other purposes and more likely to be collected and easier to maintain.

I also suspect that it may be also actually easier to collect.
