I am redoing some wiring in our house that involves breaking and
remaking some original connections -- ripping out and replacing boxes by
larger (e.g., two-gang by three-gang). I find that in some cases all the
conductors of the same color have been connected using crimps that have
then been taped over -- even the hots. Is this kosher?

Sure its kosher when its done right. BTW, high voltage, high current
cables - that is, thousands of volts and thousands of amps - use crimp
(compression) connectors.

It wasn't so much the crimping I was questioning as the two or three
layers of insulation tape vs. however many mm of insulation provided by a
wirenut.

One more time: The tape is sloppy, and if the crimp is done right, there is
absolutely no need for it.

This company makes the best crimps you can buy:

On that page, you'll see a link to a pdf file which discusses proper
crimping tools and techniques.

Although you can order directly from the company, there may also be an
industrial supply dealer near you that sells their products.
