FitContributor and min SDK support

Hi,

Sorry, I haven't got a unsupported 1.3/2.1 device (like epix) to test this.

If I use FitContributor and set the Min SDK to 1.2.x on a DataField, and then using the code (self has :createField) operator to check it exists; will this be okay on devices like Epix (or even supported devices on a older Firmware) when it comes across the using Toybox.FitContributor in the project?

I don't want to exclude these unsupported devices from using the DataField, but just not enable the FIT recording.

Cheers
Chris
