This is not possible, but would be a very useful extension of the current functionality. You should create an enhancement describing the use case in Bugzilla, and if possible, provide a patch ;-)  But also just the enhancement request would help.

Another build of your project after you have change the product?

This is only partially true: The important thing is whether the installed product has a hard or version range requirement to the feature. The instructions in Andrews blog create a version range link, which allow new versions of the feature to be installed.

The drawback of what you can currently achieve with Tycho is that this isn't particularly obvious to the users:
- Check for updates will not report new versions of the feature. For that, it would need to be listed as top-level installed feature.
- IIRC, the feature will be silently updated whenever something else is installed or updated.

So it is possible to update the feature, but I can understand if you would want the feature as top-level feature...  Your requests are all very valid, please open enhancements in Bugzilla.
