It might help us better help you if you post a screenshot of what you mean by Live Stroke Path. 

This could mean different things in different contexts. 

When creating artwork for customers to use, the rule of thumb is 'less is more.'

There are contradictory instructions on stock. You can't outline and keep them editable. I would keep them editable. The worst what could happen will be to earn a refusal. 

And yes, as @AlexBond pointed out: EPS will quite modify a lot, to keep the file visually near to the original. Upload your file as Adobe Illustrator.

Hi,
here’s a detailed guide on preparing vector files for Adobe Stock:

From there, in the section “Follow these best practices”:
- Outline all strokes as paths or shapes.

And, overall, that’s a perfectly reasonable requirement.

Besides, when you save your artwork as an EPS 10 file, all gradient strokes will automatically become separate objects anyway — EPS 10 doesn’t support gradients on strokes, as far as I remember.
