为什么 Ubuntu 20.04 中的 Vim 需要 Python 3？

我正在使用 Docker，我的dockerfile是：

######################################################
FROM ubuntu:20.04

WORKDIR /opt/test

# Apt installs
RUN apt update

######################################################

如果我构建并运行容器，然后运行以下命令，它会要求安装 python3-minimal 和 Python 依赖项：

$ docker run -it ubuntu-test
root@3a13a90d3e86:/opt/test# apt install vim

为什么 Vim 需要 Python？

（这弄乱了我的 Docker 映像，因为我实际上需要 Vim，但我还需要 32 位 Python。所以我需要 python3:i386，但 Vim 也通过安装 64 位 Python 搞乱了它）。
