DFC.....sounds like you want to be an Air traffiker........if ATC say to me no speed well thats fine by me. Normally all speed restrictions are on SID's that are totally in CAS so 250kts below Fl100 does not apply. Also I guess the speed restrictions are on the SID's to stop me catching traffic ahead....if its no speed restrictions I take it there is no conflicting traffic ahead???.....I am happy to let ATC do their job as long as they let me fly my office.
