Description of issue

I am working from behind a corporate firewall that blocks access to https://formulae.brew.sh, so I use HOMEBREW_NO_INSTALL_FROM_API=1 brew install ... to install packages. However, when I do HOMEBREW_NO_INSTALL_FROM_API=1 brew uninstall ... I get an error message about how brew is unable to access https://formulae.brew.sh:

$ HOMEBREW_NO_INSTALL_FROM_API=1 brew uninstall bash-completion
Uninstalling /home/linuxbrew/.linuxbrew/Cellar/bash-completion/1.3_3... (190 files, 623.5KB)

==> Downloading https://formulae.brew.sh/api/formula.jws.json
Error: Cannot download non-corrupt https://formulae.brew.sh/api/formula.jws.json!

Is this intentional? I understand that the environment variable is named HOMEBREW_NO_*INSTALL*_FROM_API, so is there another environment variable for the uninstall operation?
