For that matter, since both inner and outer products exist: 
https://en.wikipedia.org/wiki/Matrix_multiplication#The_inner_and_outer_products 
-> https://en.wikipedia.org/wiki/Inner_product -> 
https://en.wikipedia.org/wiki/Outer_product , if they both supported by default, none 
deserves a warning.

So, again, there should be a, say,

linear_algebra_compatibility;

compiler pragma which introduces new laws of dealing with vectors and matrices.

this does make no sense.
We can not have two binary variant, one with and one without
broadcasting.
The life of package manager is already hard to deal with dependencies,
having two flavours of octave is insane.

don't like broadcasting ?  don't use it.
Stop to boring us.
