My first exposure to ICs was largely TO-99 style "cans", followed by
flatpacks. The flatpack stuff that I had was mostly RTL. I didn't
see many DIPs until TTL. I mounted the flatpacks as surface-mount
and did a similar thing with the TO packages, just bending the leads
in an L-shape and soldering them down to the PCB pads.
That's the way I did my first IC boards--single-sided PCB, laid out
with tape and etched. Hooked the pads together with No. 26 magnet
wire.
I didn't know any better, but it worked.
