Issuing a stack dump feels ergonomically wrong when entering due to NMI.
Entering due to NMI is a normally reaction to a user request, either the NMI button on a server or a "magic knock" on a UART. Therefore the backtrace behaviour on entry due to NMI should be like SysRq-g (no stack dump) rather than like oops.
Note also that the stack dump does not offer any information that cannot be trivial retrieved using the 'bt' command.
