What's the etiquette on posting to both Stack Overflow and dev.to?

I'm fairly new to dev.to.

I love the features and UX of Stack Exchange, but have found it quite frustrating when asking questions about software architecture and design philosophies on softwareengineering.stackexchange.com not being well received.

So where dev.to has looser 'what's on topic' requirements I'm figuring I can post here.

Now the thing is - I've recently asked a pretty technically specific question that would probably be well received on Stack Overflow -but is that considered bad form, either here or there?
