Comparisons to 8.5.3 are kinda 4 years too late at this point, and as the items you wish to use are available at the press of one key, its simply a personal workflow preference you are discussing here..
all said and done, X3 is what it is. You can either use it, or not. (don't wish to sound blunt but that's where we are at). If logic or Live suit you better then use them, but accept that it is not realistic for any DAW to be the sum of all good parts of all DAWs and have no weaknesses for any one user.
I don't discredit your perceived need and have zero issues with Sonar being improved, but complaining isn't a constructive path forward so, if you have a feature request that you would like to document then the link is below. Cakewalk can then evaluate and assess the importance of any resultant change...
