When the Enerflex device was announced it was being promoted as a way
you could splice and even fish Romex without a box. (using those
articles). Then the NRTLs, U/L principally removed, the listing of
that class of device for anything but putting modular home units
together. I am not sure how the building community feels about it
today but many years ago when I was in the middle of this, they hated
the device. I am guessing it was easier to lift the listing than it
was to get a code change through the 3 year process and wait for the
states and municipalities to adopt it.
This is the listing

INTERCONNECTORS (QAAV)
GENERAL
This category covers self-contained interconnectors employing pressure
cable connectors, insulation displacement or insulation piercing
connectors
for splicing or tapping nonmetallic (NM) sheathed cable. These
interconnectors
are intended for installation in accordance with Section 336.21 and
Articles 545, 550 and 551 of NFPA 70, ‘‘National Electrical Code.’’
These devices have been evaluated for equivalency to Type NM cable in
insulation and temperature rise, and for capability to withstand fault
currents,
vibration and mechanical shock that may occur during transport of
the units in which they are use
