A professional will do anything possible to avoid going through multiple jpeg compression steps, and certainly wouldn't use software that required it as part of the workflow. Converting to/from synthetic color spaces like sRgb and AdobeRGB will be lossless aside from very minor numerical rounding issues. Converting to/from real world measured color profiles will result in visible differences after the first round trip, and will generally be unusable without significant correction after 2 or 3.
