Thanks, Jason! I appreciate any solution that does not break old code. Deprecation warnings are useful to tell you why your code is going to be broken (if informative enough) but they don't take away the necessity to change all your code, unless you have have been setting the new standard option anyway.
By the way, I don't see the problem with the current solve output of e.g. [x == 2*sqrt(y)], as this can be used as a replacement rule either by .subs() or subs_expr(). Actually, I deleted the solution_dict = True option in your example code and got the same result. Were you not aware that the arguments accepted by .subs() have changed?
