I suppose as a compromise, I could promote the use of hectoseconds instead of minutes, hours, and decimal time. Use of hectoseconds instead of minutes and hours would be an improvement and it would not change the definition of the SI time unit. SI could say that use of hectoseconds are preferred to the use of minutes and hours, but at the same time still allow people to currently use minutes and hours in connection with SI units.
