So.. how does being in a company makes you a better engineer?

For eg, this year my team shipped these 2 interesting features (among other things) that were never part of our product.
these were crazy ideas, that got liked by our users, and might have impacted the finances of company positively.

However the engineers (not me, i worked on them even less) that worked on it, did they got their knowledge growth? they just analysed the old codebase, its shitty architecture and drawbacks, and added the feature around it in a similar manner. so basically it was building debris over the debris

but is this growth? if that engg was me, would my experience in dealing with debris and building debris over it (that somehow works) be helpful for any other organisation?

And number (2) : is my organisation even a good one if its allowing to build debris over debris and not leaving a space for discussion or cleaning the mess or thinking about better architectures, data structures for scalability and robustness?

An engineer's growth should be made by giving them a chance to explore new and best solutions and not the best hacks i guess
