Whenever further editing needs to be applied in another application, an output colour profile is only necessary IF the second application can only read image formats with a colour profile attached, or you have already done some necessary colour adjustments.
If one takes one's most heavily edited image in Dt, and look at the [ show only active modules ] tab, one will see that the [ input colour profile ] occurs immediately before the first colour correction module, and the [ output colour profile ] module is one of the last modules, occurring after the last colour correction module. Most of the actual development takes place BEFORE colour profiles are even considered. Raw black/white point, white balance, (which has to do with the relative level of RGB response, and not the actual values of R, G, and/or B), highlight reconstruction, (again, relative response), demosaic, (again, relative), orientation, crop and rotate, retouch, and exposure, all come before input colour profile, (and is NOT an exhaustive list). If no colour work is being done before the next application, then a linear colour workflow format such as OpenEXR is more than adequate, and highly recommended, (by me, and industry creatives). If one has done some colour work, and there is more colour work to be done, (or if the next application cannot read OpenEXR, or other linear colour model formats) then I highly recommend a high colour gamut profile such as ProPhotoRGB. If any other processing does not involve colour work, (such as, you are the final colour grader), then use an appropriate output colour profile such as sRGB, unless that is someone else's job to decide, based on expected usage.
