[git-sizer] Implications of a large commit object

[Lars Schneider <larsxschneider@gmail.com>]

Hi,

I am using Michael's fantastic Git repo analyzer tool "git-sizer" [*]
and it detected a very large commit of 7.33 MiB in my repo (see chart 
below).

This large commit is expected. I've imported that repo from another
version control system but excluded all binary files (e.g. images) and
some 3rd party components as their history is not important [**]. I've 
reintroduced these files in the head commit again. This is where the 
large commit came from.

This repo is not used in production yet but I wonder if this kind of
approach can cause trouble down the line? Are there any relevant
implication of a single large commit like this in history? 

Thanks,
Lars

[**] I know some of this stuff shouldn't be in the repo in the first 
     place, but I am constrained in the things I can change.
