Can I only use modules based on revision 3 nRF51822 with nRF51-DK ??

Question

I guess and hope not but I am a little confused by the compatibility matrix..
 
 I would need to use SDK 7 or higher for my nRF51-DK
but I would need to use SDK6.1 or lower to work with my revision 2 based nRF51822 modules? 
 Can I use the nRF-51DK to programm and debug my revision 2 modules?? 
And only need to switch between SDKs for the DK and the modules? 
 And what do I miss with only revision 2 of nRF51822? Latest usable SDK6.1?

Hi. In addition to Mangos comment: This document describes what's new in the third revision and hence what you "miss out on" using revision 2. In the release notes bundled with the various softdevices you will also find a chapter on new functionality for that particular Softdevice. We don't recommend using incompatible Softdevices, SDKs and IC revisions. Maybe it works for you and maybe it doesn't. What is sure is that we have not tested it and won't make any guarantees. 
 Answer to comments below: 
 The SD 8.0.0 is tested and proven to work on rev 2 ICs. The SDK, on the other hand (which is just a set of libraries, drivers and examples), is not tested. Hence you can safely use SD v8, but you can't base your application on SDK v8 and expect it to work. You will have to write your own drivers, libraries and application from scratch, which is a lot of work. 
 In other words, the SDK is dependent on the SD, as it uses a lot of the functions in the SD, but the SD is not dependent on the SDK. 
 The nRF51 DK can be used with any SD and SDK compatible with revision 3 ICs. 
 You can use SDK 6.1.0 and SD 7.1.0 on both IC revision 2 & 3 according to the compatibility matrix. Revision 2 ICs have some issues with the I2C (aka TWI) and UART. Check out the Product Anomaly documents to learn more. To accommodate for these anomalies you should use the latest SDK, SD and IC revision if you can.
