Yes, this is the "tip of the iceberg". There is a large array of surveys that has been growing in number and complexity for many decades (i.e., it didn't start with Bush, or Clinton, or any of the latest bugaboos of one or the other of the "big tent" parties).

In some ways, the surveys are LESS intrusive now than they have been in the past. For example, until the 1930's, there was a decennial census of religion.

Whereas now, such collection, at least on a "mandatory" basis, is deemed illegal:
Information on religion

Information on religion
Answer
The U.S. Census Bureau does not collect data on religious affiliation in its demographic surveys or decennial census. Public Law 94-521 prohibits us from asking a question on religious affiliation on a mandatory basis; in some person or household surveys, however, the U.S. Census Bureau may collect information about religious practices, on a voluntary basis. Therefore, the U.S. Census Bureau is not the source for information on religion, nor is the Census Bureau the source for information on religious affiliation. Some statistics on religion can be found in the Statistical Abstract of the United States, Section 1, Population. In addition, we do provide a list of contacts for further assistance regarding religious information.
We do publish economic data on Religious Organizations down to the county and ZIP Code level in the County Business Patterns series. Religious organizations are comprised of (1) establishments primarily engaged in operating religious organizations, such as churches, religious temples, and monasteries and/or (2) establishments primarily engaged in administering an organized religion or promoting religious activities. Additionally, the County Business Patterns series provides data on used merchandise stores that are operated by religious organizations.

Yep, actually the questions on the long form (the ACS is REPLACING the long form, nobody will get those in 2010) have been REDUCED.
