This is perfectly fine with a proper content wise setup. I think, in the short term it is valid to see it like this. In mid- to longterm view it will become a problem:
- You have to manage more and more content in an less optimal way,
- it will be hard to find designers or content managers who can work with this,
- It will be harder to find errors or bugs in your code/site, when they occur and you look for the reason/source of the problem and last but not least
- Other people can help less/way harder because they don’t expect your setup to be like this and there might be lot of undocumented/uncommon implementations which are hard to understand without a complete view on the whole project every time you have an issue.
So yes, it is a way to start or to test how things work but it will raise issues and complexity very quick and this should be prevented at the most earliest stage to make your own life easier. Otherwise your current problems or questions will look like tiny ones compared to what might come next lol.
