Design patterns are a starting point –– a template, not a complete solution. As most things, there are tradeoffs with each decision.
When evaluating whether a decision is “okay” or not for a given question, I normally ask two questions,
-
“Does it violate SOLID?”
-
And if it does, “Am I okay with the consequences that will result?”
I go into more details about SOLID on this thread.
TLDR:
It’s probably okay, as long as you understand the consequences of doing so. If you anticipate a problem that it will cause, design for it.
