You are not correct. Those effects are considered in PDN analysis and there is
work published on that.
Search for terms like "Dissipative Edge Termination". There is paper from Novak
on that topic if I remember.
The reason why you do not see this topic discussed in most designs is probably
because their impact is very small compared with trying to keep the PDN
impedance bellow the target but there are some niche applications where they
have an impact.

Subject: [SI-LIST] Transmission Line Effect in PDN
Guys,
Can anyone explain that why don't we consider transmission line effects ( like
reflection, length of line, termination of line ) in power delivery network
(PDN) analysis ?
Why in PDN all effort is to reduce PDN impedance and no one talks about above
mentioned transmission line effects ??
