The following works as expected.

\def\startsplit
   {\startalign[*]} % no number by default

\def\stopsplit
   {&\doalignNR[+][]\crcr % for a number on last line
    \stopalign}

\placeformula \startformula \startsplit
  a &= b \\
    &= c
\stopsplit \stopformula

It seems that you are still thinking about [#2] in the definition of 
\definealign. Can it be such that,

\definealign[gather][n=1,align={middle}]
\definealign[lgather][n=1,align={left}]

\startformula \startgather
  a = b + c \\
  e = f
\stopgather \stopformula

results in center aligned equations
   a = b + c
     e = f

and

\startformula \startlgather
  a = b + c \\
  e = f
\stoplgather \stopformula

results in left aligned equations

  a = b + c
  e = f

Thanks,

Aditya
