[FieldTrip] Variable Number of Tapers in 'mtmfft' Frequency Analysis

Hi Fieldtrip users,

ft_freqanalysis (FT version 20170404) does not allow using a variable
number of tapers in 'mtmfft' mode (lines 462-465 display a warning and keep
only the first element of cfg.tapsmofrq), but it seems like
ft_specest_mtmfft does have an implementation of a variable number of
tapers (lines 286-348). It also seems like mtm_specest_mtmconvol, which
allows variable number of tapers, calls ft_specest_mtmfft. So 2 questions:
1. Is the variable number of tapers option used in mtmfft in some other way?
2. What is the reason for not allowing a variable number of tapers in
mtmfft generally?
