Hi Brady,

I think is a good idea, I agree. The simpler the better.


Best regards,

David.

Asunto: [sfc-dev] Deprecating SFC, SFP, and RSP symmetric fields


Currently there is a symmetric field in the SFC, SFP, and RSP data
models. I will deprecate these fields now in Carbon.

Instead of defining this in one of [SFC, SFP, RSP] a chain will be
symmetric if it has an SF whose SF-type has the symmetry flag set to
true. The SF-type symmetry field was also added in Beryllium.

It was always confusing what it meant if there is some combination of
symmetric values for the SFC, SFP, and RSP. That is, what if
SFC:symmetric is true, SFP:symmetric is false, and RSP:symmetric is
true? Or some similar combination?

Currently, a reverse RSP is created if the SFP symmetric field is true.
This will still be the case in Carbon, but we will also check the
SF-types as explained above. In Nitrogen, we'll remove the SFP symmetric
field check.

I've already updated the SFC Carbon Release Plan to mention these
deprecated fields.

Regards,

Brady
