VTP : Transparent Mode

I understand the text book defination and function of transparent mode.
But could someone please try and explain a "real life" situation where you would set a switch up in transparent mode for a specific purpose?

Obliged,

One reason that I understand where one would configure a switch for transparent mode is for example the "Accounting" VLAN. Since that VLAN would only exist on that switch only and NOT propagated up to the VTP Server or down to the VTP Client switch, there shouldn't be a way to networkingly "hack" into say, the Payroll computer by employees so that they can modify their payrate data so their paychecks will be bigger.

VTP Clients and Servers alike are both vulnerable to unintended overwrites of their vlan database. VTP Transparent mode allows a switch to create, modify, and delete vlans without being vulnerable to an overwrite.

We use transparent mode here because we don't want every vlan going to every switch. We only want them to go where they are needed (there are a lot of vlans here). Not to mention, there's a mix of vendors here, so it wouldn't work on half of our switches, anyway.
