Using extras not to install things

[dinjazelena]

Hey, so for example, i am maintaining library which can be used on Databricks, which means most of the preinstalled stuff on Databricks should not be installed on Databricks again. For example pandas...
I want to have as my main dependency pandas, cos lib could be used everywhere.
But if i want to install it on databricks with pip install lib[databricks] i want it not to install pandas.

I know that if i want to specify it as extras outside of main. But then if i want to install it anywhere outside of Databricks i would have to use extras.
