WRITE_EXTERNAL_STORAGE provides write access to emulated SD card ("internal storage"). However for some reason it provides only read access to real SD card. This is what happen before and after WRITE_EXTERNAL_STORAGE is granted respectively on my phone:
$ id
uid=10312(u0_a312) gid=10312(u0_a312) groups=10312(u0_a312),3003(inet),9997(everybody),20312(u0_a312_cache),50312(all_a312)
$ ls -ld /storage/emulated/0
drwxrwx--x 87 root sdcard_rw 4096 Jul 2 15:17 /storage/emulated/0
$ ls -ld /storage/3436-3531
drwxrwx--x 5 root sdcard_rw 32768 Jan 1 1970 /storage/3436-3531

As you can see, although both storage paths' owner group changes from "sdcard_rw" to "everybody" after the permission is granted, the group permission of that of the real SD card changes from rwx to r-x.
From the data/etc/platform.xml in current platform/frameworks/base master, I can see that the group "sdcard_rw" (along side with "media_rw") is provided by an undocumented permission named WRITE_MEDIA_STORAGE. Therefore, proposing to add the permission to the manifest.

@intuited That requires root. Since Termux is primarily for non-rooted users, we are not going to bloat application with useless permissions. |

Not tested so I have no idea if it actually works as expected. Would be great if someone at liberty to build the app can help test this.
