You can use a container as a single environment in which to do development, and that works fine. But they are by definition an isolated environment with different dependencies than other containers. The result of compiling something in a container necessarily needs to end up in its own container.
...that said, you could use the exact same container base image, and make many different container images from it, and those files would be compatible (assuming you shipped all needed dependencies).

You can absolutely mix and match lots of different binaries from different sources on one Linux system. That's exactly what we're doing now with TCL modules.

Well yes, that's the problem. You end up either putting everything in one container (in which case why bother with a container?), or with a combinatorial explosion of every piece and version of software you might use.
TCL modules are better. They don't let you cheat like containers do, but in return you get a better system.
