Do note I didn't mention any specific variable names.
And I've explicitly outlined exactly the case you are describing in your post
- integration.
If you indeed have "more other" applications (native ports of certain tools,
which still use environment as a go-to reference sources), then by all means,
do what you find best for you.
I do that all the time, too, but I also have Cygwin itself configured to match
the environment I expect to have. Just to avoid issues.
