One possibility for complete generality could be to align on how it is
described by EPSG:
(or more readable in "184.108.40.206 Transverse Mercator Zoned Grid System" in
And a more understandable example:
So that could be
+proj=tmerc +lon_0=-180 +lat_0=0 +w=6 +k_0=0.9996 +x_0=500000 +y=0
The presence of the parameter w= could be the one that triggers the automated
But yes as the only practical use is UTM, "+proj=utm +zone=auto [+south]"
could be used as a shortcut.
