Nope. Unless practicing a max-rate descent, descending out of CAS was always TA/RA as was the recovery (joining the hold) until it got so busy with a mix of Visual and instrument traffic. If that traffic wasn't there, you could comfortably stay TA/RA throughout, but if it was there and a spritely Tutor got 'too close' the implication of a full RA could have been far more of an issue than simply 'seeing and avoiding'.
Of course if it got too busy you may have been better to have gone elsewhere!
