Key word = Modernist.
If it's un-modern (pre-modern), it's suspect. Thus, "conservative" Catholics (lovers of all things JP2 but little or nothing before 1978) are often quite devoted to the Divine Mercy Chaplet (a repetitive devotion) and will substitute that for the rosary, as if the former is equivalent or even "better." Recently, someone prominent in our trad parish was quite ill and needed prayers. The prayer tree specified "Masses," "Rosaries," etc. Along came a N.O. Mass attendee and asked specifically to substitute a D.M. chaplet for the latter, even though the prayer cards had already been written out. Modern substitutions are something of a cult for many of these people. Generally, they fall into 2 categories: no sacramentals and devotions at all, or only modern ones and modern "Saints."
That's just my experience, but one I have consistently encountered.
