I think yes. The project requires only one dependency instead of two
(TAChart+AggPas). So this might actually be an advantage.
The other possibility is to use conditionals and let the project enable it via
switches. But this is less safe, aka more things can go wrong. For example the
programmer might setup the dependencies in the wrong order and will get
unit-not-found errors, which will not be helpful.

What should that be?
Packages are shown alphabetically, so if you use the same prefix they are listed
close together.
