True that, but not to worry.
In order for an extreme K separation to work reliably, the TAC will
have to be set far lower than the specified TAC of the publication.
Something like 240 or 260. The goal is to create a profile that
generates a black channel that is a near perfect grayscale of the
image. Setting the TAC at 300 or above will give the CMY inks too
much room to move upwards. BTW, simply using a heavy GCR doesn't
quite do the job and a quick curves experiment in Photoshop to
simulate gain should reveal this.
Admittedly, the extreme K separation is a very sad (though
interesting) pre-press futz and a very non-conventional use of color
management.

TAC (Total Area Coverage, which is another
way to refer to the Total Ink Limit) is acceptable on the magazine
paper
stock on which the image is going to be printed. In other words,
you should
not build a file with a 315% TAC if the paper stock can only safely
hold a
maximum of 300%.
