I not sure this is a good idea. Isn't this the only way of providing feedback about whether the symbols were actually added? If we are unable to load the symbol file specified (perhaps because the user made a typo, or the file is corrupted), then the symbol vendor will just create a default SymbolFile backed by the original object file. Doesn't that mean this will basically always return true now?<br>
<br>
I think this is strictly worse that the previous solution as it lets the objectless-symbol-file hack leak out of SymbolFilePDB.<br>
