Should Panchira (Panty Shots) be considered porn?

[Apocist]

Panchira, Panty Shots, Flipped Skirts, and Fan Service are an illustration/media representation well used in much old and new mainstream anime, manga, and art.

Some more linked details on what panchira is at https://en.wikipedia.org/wiki/Panchira and https://animanga.fandom.com/wiki/Panchira.

Both a large number of well-known family friendly and more adult anime make use of this tact. While a very small and exhaustible list of shows with such content, some series can be found here: https://www.anime-planet.com/anime/tags/panty-shots. (some series may obviously be more ecchi in nature)

With other's opinions on the matter, do you think this style of media should be considered pornographic?
