Why are there limits?

Theme limits are enforced for a few different reasons:
For security purposes it’s important to vet the types of files that customers are
allowed to upload so that we don’t receive malicious files.
To prevent misuse or abuse vectors, it's important to limit the total size of
files.
For performance reasons, it’s important to serve, save, import and export files
quickly for customers.
