Yes, append == incremental update. Incremental update doesn't break a signature - since it doesn't change the byte range that was signed. HOWEVER, depending on what you change with that update you MAY cause it to become invalid.
How? Because if the certification bits (Perms) say not to allow form filling and you fill in some forms, then you've broken it. BUT if you are allowed to fill forms and ALL YOU DO is fill fields, then that's perfectly fine.

Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
