This "feature" (temporarily disable wifi or bluetooth) could be present somewhere in settings. However, the quick-access on/off should be the simple on/off.What feature do you "think" you lost? Actually We gained a feature. One I and many other use every day. Maybe you'd prefer Android. Best of luck.
BTW, most commenters here, who are calling the present behavior a feature, should actually make themselves acquainted with the wi-fi assist feature, which exists since iOS 9, and does exactly what they claim this "new feature" is bringing them.

Apple has done lots of research around this, which have resulted in the change of function. What they found is that the VAST MAJORITY of users just want to disconnect from the current wifi, not turn it off completely.
Please understand this change was made based on the usage of most users. This may not reflect your own usage but sadly, changes are made to help the majority of users, not the minority.
And you claim this based on what?
Even if Apple indeed analyzed usage data, they most probably have no way of knowing that a user actually wanted to do something else than what he actually did.
Moreover, the usage data Apple could use, would not contain the usage data from the *sane* users, who naturally disable any usage-data sharing with Apple or anyone else.
