Shen told The Register 4G feature phones have until recently used the QQVGA standard for their displays – meaning developers only had 160 x 120 pixels to work with. QVGA jumps to 320 x 240 resolution, which he believes makes accessing the web on a feature phone at least a little bit more appealing.
I cannot imagine browsing the web on 320x240, let alone 160x120.
While I could see this being used in specific uses cases (for children, people with legal restrictions) and in the entry level market in some developing countries, I don't think feature phones can "rise again".
I am sure the people who are buying these 4G feature phones will switch to a regular super budget smartphone as soon they are able to find the money for it.
